IMPROVEMENT IN INS/OLES OF BOOTS AND SHOES.

Specication thrilling part of -Lctters Patent No. 209,184, dated October 22, 1878; application filed February 15, 18778.

To all lwhom it may concern:

Be it known that I, J oHN F. NIcKERsoN, of Lynn, in the county of Essex and State of Massachusetts, have invented a new and useful Improvement in Insoles for Boots or Shoes; and do hereby declare the same to be described in the following` specification and represented in the accompanying drawings, of which- Figure l is a transverse section, and Fig. 2'

and composing such insole, as described.

In the drawings, Figs. l and 2, A and B denote the two leather layers of the insole, C being the metallic plate arranged between them.

Fig. 3 is a top view, Fig. 4 a transverse section, and Fig. 5 a longitudinal section, of the upper layer, A. Fig. 6 is a top view of the metallic plate C, that goes between the two layers A B. Fig 7 is a top view of the heel reenforce plate.

The two layers A B, I usually make of leather, though cloth may be substituted,and I arrange the metallic plate G between them, it being formed so that they may extend beyond it at itsiedge or edges and lap on cach other, the laps being fastened together by cement or by stitches passing through them. The upper, which is thc thicker of the two layers, I channel or groove around it and near its edge, except in the heel portion, such groove being shown at a, and being for the purpose of receiving the sewing used in connecting the layers, and also that (shown at b) employed in connecting the insole, the upper I), and the outer sole, E. This groove is to prevent the stitches from projecting above the upper surface of the insole to cause the lining F of the insole to bulge upward more or less over the sewing.

The outer edge of the layer A is rounded, as shown at c, in order to prevent it from cutting the cloth lining d of the upper when the shoe may be in use.

usually do when the insole is made of one single piece or layer of leather.

The outer sole is to be channeled or grooved in the usual way to receive the stitches, and it is to be fastened to the upper and the insole by stitches b passing through them andinto the channels of the insole and outer sole, such sewing being accomplished by a McKay sew- Y ing-machine. y

Besides the metallic plate C, arranged between the two layers A B of the insole, I reenforce the heel part of such insole by one or more metallic plates, F, arranged within such heel, in manner as shown.

Sometimes I extend the re-enforce forward more or less into the shank of the insole. The

re-enforce is to prevent the nails used in tX- ing the heel to the shoe from being driven through the insole, they, while being driven, being clinched by the re-en'force.

The metallic plate used should be thin, so as to be suflicicntly flexible or elastic.

I do not broadly claim an inner sole composed of two layers of leather or other like material anda sheet of metal interposed be-v tween them, and arranged so that the two layers may extend beyond its edge and`lap on each other, as set forth.-

I claim as my invention as follows:

1. An insole composed of a sheet of metal and two layers of leather or other suitable material, arrapged as set forth, and' having the `upper of said layers grooved or creased on its upper surface and rounded -on its ed gc, as specilied.

2. The combinationl of one or more re-enforce metallic plates, F, arranged in the heel ofthe insole, with the metallic plate C and the two layers A B, arranged and composing such in'- sole, substantially as specified.
